Lunar Atmosphere and Dust Environment Explorer 2010-present

LADEE

The Lunar Atmosphere and Dust Environment Explorer (LADEE) is designed to study the Moon’s this exosphere and the lunar dust environment.  The orbiter will determine the density, composition and temporal and spatial variability of the Moon’s exosphere to help us understand where the species in the exosphere came from as well as the role of the solar wind, lunar surface and interior, and meteoric infall as sources.  The mission will also examine the density and temporal and spatial variability of dust particles that may get lofted into the atmosphere.  Because the Moon’s atmosphere is so thin, disturbances could quickly swamp its natural composition.

The mission will also test several new technologies, including a modular spacecraft bus that may reduce the cost of future deep space missions and demonstrate two-way high rate laser communication for the first time from the Moon.

In addition to supporting  the ITOS system as the standard TT&C for all Integration and Test, Mission, Science and LaserComm Operations

Lunar Reconnaissance Orbiter (LRO) 2006-present

LRO Concept Image

The Lunar Reconnaissance Orbiter (LRO) is a robotic mission that set out to map the moon’s surface and, after a year of exploration was extended with a unique set of science objectives.  LRO observations have enabled numerous groundbreaking discoveries, creating a new picture of the Moon as a dynamic and complex body.  These developments have set up a scientific framework through which to challenge and improve our understanding of processes throughout the solar system.

The LRO instruments return global data, such as day-night temperature maps, a global geodetic grid, high resolution color imaging and the Moon’s UV albedo.  There is particular emphasis on the polar regions of the Moon where continuous access to solar illumination may be possible and the prospect of water in the permanently shadowed regions at the poles may exist.

Hammers was the developer of the flight software for this mission, including attitude, determination & Control (ACS) and command and Data handling (CD&H) in real-time. Additionally, Hammers developed the ground software command and telemetry System.  For the LRO mission, Hammers designed and delivered 18 spacecraft simulators with MIL STD 1553 and SpaceWire data interfaces for the mission team.  We also served in a lead role on the Ground System Refresh and virtualization effort that began in 2012.

USGS Landsat 8

Landsat 8Landsat represents the world’s longer continuously acquired collection of space-based moderate-resolution land remote sensing data.  Four decades of imagery provided a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research.  Landsat images have proven invaluable for emergency response and disaster relief.  As a joint initiative between the U.S. geological Survey (USGS) and NASA, the Landsat Project and the data it collects support government, commercial, industrial, civilian, military, and educational communities throughout the United States and worldwide.   The Landsat 8 satellite images the entire Earth every 16 days in an 8-day offset from Landsat 7.

The Landsat 8 OLI/TIRS Pre-WRS-2 data set contains nearly 10,000 scenes acquired by the Operational Land Imager (OLI) and/or Thermal Infrared Sensor (TIRS) sensors after launch (February 11, 2013) through April 10, 2013, the satellite achieved operational orbit (WRS-2).

Hammers designed and implemented the Mission Operations Element (MOE) for this first class NASA mission.  The system incorporates the latest technology in virtual servers for Telemetry and Command, Flight Dynamics, Planning and Scheduling, and System Automation.

NASA Fermi (GLAST)

FermiNumerous exotic phenomena occur in space and some of these can generate almost inconceivable amounts of energy.  Some of these phenomena include, supermassive black holes, merging neutron stars, and streams of hot gas moving at the speed of light.  The Fermi Gamma-ray Space Telescope, formerly GLAST, is opening the high-energy world of space to exploration and helping to answer important questions.  Questions including, what is happening to produce the amount of energy, what happens to the surrounding environment near those phenomena, and how will studying the energetic objects ass to the understanding of the nature of the universe and how it behaves.

With Fermi, astronauts can finally have a tool to study how black holes, known for pulling matter in, can accelerate jets of gas outward at extremely high speeds.  Physicists are able to study subatomic particles at energies far greater than those seen in ground-based particle accelerators.  And cosmologists are gaining valuable information about the birth and early evolution of the Universe.  For this endeavor, one that brings together the astrophysics and particle physics communities, NASA has teamed with the U.S. Department of Energy and Institutions in France, Germany, Japan, Italy, and Sweden.

NASA THEMIS/ARTEMIS

ThemisThe Time History of Events and Macroscale Interactions during Substorms (THEMIS) is a mission to investigate what causes auras in the Earth’s atmosphere to dramatically change from slowly shimmering waves of light to wildly shifting streaks of color.  Discovering what causes auroras to change will provide scientists with important details on how the planet’s magnetosphere works and the important Sun-Earth connection.

Themis is a 2 year mission consisting of 5 identical probes that will study the violent colorful eruptions or Auroras.  Understanding and predicting the weather is important to describe the environment in which spacecraft and astronauts operate and ensure their safety.  Just as hail and tornadoes accompany the most severe thunderstorms, substorms accompany the most intense space storms; those that disrupt communications, cause power line transmission failures, and produce the most penetrating radiation.  THEMIS will study substorms to gain insight into the most severe space storms.  With THEMIS, for the first time NASA will launch a constellation of five satellites to study substorms.

The Hammers Company designed, developed, integrated and tested the flight software which included the attitude control and command and data handling on-board systems.  Hammers also used our ITOS command and control system for spacecraft integration and test, launch and early orbit operations and is the mission operations system for the constellation. As part of continued real-time operations support, Hammers flight software engineers developed and uploaded new control algorithms in two of the spacecraft to move them into a lunar orbit for the ARTEMIS mission requirements.

NASA Swift

SwiftSWIFT is a MIDEX Gamma Ray Burst mission led by NASA with participation of Italy and the UK.  SWIFT is a mission that was dedicated to the observations of Gamma-ray bursts (GRBs), although, throughout the life of this mission a lot of challenging non-GRB science has been performed.  GRBs are the most powerful explosions the Universe has seen since the Big Bang, occurring about once a day.  They are brief, but intense flashes of gamma radiation, coming from all different directions of the sky and last from a few milliseconds to a few hundred seconds.  To date, scientists do not know what causes them.

With SWIFT, launched in November 2004, scientists now have a tool dedicated to answering the many questions and solving the gamma-ray burst mystery.  SWIFT relays a burst’s location to ground stations within seconds after the burst onset, allowing both ground-based and space-based telescopes around the world the opportunity to observe the burst’s afterglow.  The instruments are on board SWIFT include the Burst Alert Telescope (BAT), the X-Ray Telescope (XRT), and the Ultra Violet-Optical Telescope (UVOT).

Hammers provided VirtualSat® to support operations for slow commanding to institute science observations.

NASA ICESAT-2

ICESat-2ICESat-2 is a continuation of the global time series of precision ice topography measurements initiated but the first ICESat mission.  It has been extended in selected areas by the IceBridge projects, a series of ongoing surveys of polar areas using aircraft-borne instruments.  The first ICESat was on orbit from 2003-2010, and provided invaluable data needed to assess ice sheet mass balance, sea ice thickness, and to estimate biomass.

ICESat -2 will use improved precision laser-ranging techniques to measure the topography of the Greenland and Antarctic ice sheets and the thickness of sea ice.  ICESat-2 will help scientists develop a better scientific understanding of the Earth system and its response to natural or human-induced changes.

NASA CYGNSS

CYGNSSThe Cyclone Global Navigation Satellite System (CYGNSS) aims to improve extreme weather prediction.  This project uses a constellation of eight satellites carried into orbit on a single launch vehicle.  While in orbit, CYGNSS’s eight micro-satellite observatories will receive both direct and reflected signals from Global positioning System (GPS) satellites.  The direct signals pinpoint CYGNSS observatory positions, while the reflected signals respond to ocean surface roughness which is received from wind speed.

This mission of CYGNSS is to study the relationship between ocean surface properties, moist atmospheric thermodynamics, radiation and convective dynamics to determine how a tropical cyclone forms and whether or not it will strengthen, and if so, by how much.  This data will advance forecasting and tracking methods.

The satellites are expected to launch in 2016.

NASA ICON

ICONThe Ionospheric Connection Explorer will explore the boundary between Earth and space, the ionosphere, in order to understand the physical connection between our world and the immediate space environment around us.  In this region, where ionized plasma and neutral gas collide and react, exhibits dramatic variability that affects space-based technological systems like GPS.  The ionosphere has been known to respond to “space weather” drivers from the sun, but recent NASA missions have shown this variability often occurs in connection with weather on our planet.  ICON will compare the impacts of these two drivers as they exert change on the space environment that surrounds us.

NASA SAMPEX

SAMPEXThe Solar Anomalous and Magnetospheric Particle Explorer (SAMPEX) was an international collaboration between NASA of the United Stated and Germany.  It was the first of SMEX’es (Small Explorers), and was launched in July 1992, carrying four instruments and aimed to fly in low orbits.  SAMPEX studies the energy, composition, and charge states of particles from supernova explosions, from the heart of solar flares, and from the depths of nearby interstellar space.  It also closely monitors the magnetospheric particle populations which sometimes drop into the middle atmosphere of the Earth, thereby ionizing neutral gases and altering the atmospheric chemistry.  One of the key elements of SAMPEX is to use the magnetic field of the earth as an essential component of the measurement strategy.

Over the next several years, as the solar activity ramps up to its 11-year maximum, SAMPEX investigations will survey the acceleration of the relativistic electrons, measure their impact on the upper atmosphere, and determine their influence on atmospheric chemistry not only for solar minimum conditions but also for the more complex solar active periods; obtain samples of solar material from dozens of flares; measure the anomalous component isotrophic composition, trapping lifetime, and disappearance near solar maximum; and to serve as a unique link in the chain of observatories put in place by NASA and its international partners to study space weather during upcoming solar maximum.  Most of these investigations can only be carried out using SAMPEX’s unique orbit and highly sensitive detectors.

NASA SWAS

SWASThe Submillimeter Wave Astronomy Satellite (SWAS) was launched in December 1998 into a low Earth orbit.  This was a part of the Small Explorer (SMEX) mission and was originally planned for two years, but SWAS made observations until July 2004.  The goal of this mission was to gain a greater understanding of star formation by determining the composition of interstellar clouds and establishing the means by which these clouds cool as they collapse to form stars and planets.

After over six years of science observations, SWAS achieved and exceeded its original goals.  It made detailed maps of many giant molecular and dark cloud cores, it observed the atmospheres of Mars, Jupiter, Saturn and several comets, and made other key discoveries.  One of these discoveries is that water is prevalent throughout space, it was detected in almost every dust cloud in space it observed.

Utilizing the ITOS command and control ground system, Hammers supported spacecraft integration and test, launch and early orbit mission operations.

NASA TRACE

TRACEThe Transition Region and Coronal Explorer was launched in April 1998, with the objective to explore the three-dimensional magnetic structures which emerge through the visible surface of the Sun and define the geometry and dynamics of the upper solar atmosphere.  The TRACE data provided quantitative observational constraints on the models, leading to real advances in our understanding of the transition from low to high beta plasma.  The solar atmosphere is constantly evolving because the magnetic field which dominate the Corona are continuously being displaced by the convective motions in the outer layers of the Sun just below the Photosphere. One of the major objectives of the TRACE investigation was to explore the relation between diffusion on the surface magnetic fields and the changes in heating structure throughout the Transition Region and Corona.  The simultaneous movies of the 6000 to 10,000 degrees K volume of the solar atmosphere allowed us to determine the rate of change of the magnetic topology and the nature of the local restructuring and reconnection processes.

As part of the NASA Small Explorer (SMEX) team, Hammers supported development of the flight software for attitude control and the command and data handling systems. Utilizing the ITOS command and control ground system, Hammers supported spacecraft integration and test, launch and early orbit mission operations.

NASA WIRE

WIREThe Wide-field Infrared Explorer (WIRE) was a small satellite carrying cryogenically cooled infrared telescope designed to study starburst galaxies, vast clouds of molecular gas around the sites of newborn starts.  WIRE was developed under NASA’s Small Explorer Program (SMEX) and was launched in March 1999.  Due to an equipment malfunction, the telescope’s coolant was delpleted quickly shortly after its launch, thus it was unusable for its original mission.  WIRE has since been repurposed to use on onboard Star Tracker for long-term monitoring of bright stars.
