GREENBELT, Md. (NASA PR) — After a successful launch on April 18, 2018, NASA’s newest planet hunter, the Transiting Exoplanet Survey Satellite, is currently undergoing a series of commissioning tests before it begins searching for planets. The TESS team has reported that the spacecraft and cameras are in good health, and the spacecraft has successfully reached its final science orbit. The team continues to conduct tests in order to optimize spacecraft performance with a goal of beginning science at the end of July.

Every new mission goes through a commissioning period of testing and adjustments before beginning science operations. This serves to test how the spacecraft and its instruments are performing and determines whether any changes need to be made before the mission starts observations.

TESS is a NASA Astrophysics Explorer mission led and operated by MIT in Cambridge, Massachusetts, and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Dr. George Ricker of MIT’s Kavli Institute for Astrophysics and Space Research serves as principal investigator for the mission. Additional partners include Northrop Grumman, based in Falls Church, Virginia; NASA’s Ames Research Center in California’s Silicon Valley; the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts; MIT’s Lincoln Laboratory in Lexington, Massachusetts; and the Space Telescope Science Institute in Baltimore. More than a dozen universities, research institutes and observatories worldwide are participants in the mission.

GREENBELT, Md. (NASA PR) — New tracking data confirms that NASA’s OSIRIS-REx spacecraft successfully completed its second Deep Space Maneuver (DSM-2) on June 28. The thruster burn put the spacecraft on course for a series of asteroid approach maneuvers to be executed this fall that will culminate with the spacecraft’s scheduled arrival at asteroid Bennu on Dec. 3.

The DSM-2 burn, which employed the spacecraft’s Trajectory Correction Maneuver (TCM) thruster set, resulted in a 37 miles per hour (16.7 meters per second) change in the vehicle’s velocity and consumed 28.2 pounds (12.8 kilograms) of fuel.

Tracking data from the Deep Space Network provided preliminary confirmation of the burn’s execution, and the subsequent downlink of telemetry from the spacecraft shows that all subsystems performed as expected.

DSM-2 was OSIRIS-REx’s last deep space maneuver of its outbound cruise to Bennu. The next engine burn, Asteroid Approach Maneuver 1 (AAM-1), is scheduled for early October. AAM-1 is a major braking maneuver designed to slow the spacecraft’s speed from approximately 1,130 to 320 miles per hour (506.2 to 144.4 meters per second) relative to Bennu and is the first of four asteroid approach maneuvers scheduled for this fall.

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering and the safety and mission assurance for OSIRIS-REx. Dante Lauretta of the University of Arizona, Tucson, is the principal investigator, and the University of Arizona also leads the science team and the mission’s observation planning and processing. Lockheed Martin Space in Denver built the spacecraft and is providing spacecraft flight operations. Goddard and KinetX Aerospace are responsible for navigating the OSIRIS-REx spacecraft. OSIRIS-REx is the third mission in NASA’s New Frontiers Program. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the agency’s New Frontiers Program for its Science Mission Directorate in Washington.

NASA established the Independent Review Board (IRB) in April to evaluate the space agency’s $8 billion James Webb Space Telescope (JWST). The report, released last month, revealed a number of eye opening details about problems that NASA and the prime contractor, Northrop Grumman Aerospace Systems (NGAS), have been experiencing in building the telescope and managing the program. Below are some key excerpts.

Independent Review Board Report
NASA James Webb Space Telescope

Full Report

Selected Excerpts

There have been several JWST Project problems due to human-induced errors that had substantial cost and schedule impact. In one case, an improper solvent was used to clean propulsion system valves that had been stored. The error was a failure to check with the valve vendor to ensure the solvent to be used was recommended and would not damage the valves. The valves had to be removed from the spacecraft, repaired or replaced, and reinstalled.

Martian Dust Storm Grows Global: Curiosity Captures Photos of Thickening Haze

In June 2018 NASA’s Curiosity Rover used its Mast Camera, or Mastcam, to snap photos of the intensifying haziness the surface of Mars, caused by a massive dust storm. The rover is standing inside Gale Crater looking out to the crater rim. The photos span about a couple of weeks, starting with a shot of the area before the storm appeared. (Credits: NASA)

GALE CRATER, Mars (NASA PR) — A storm of tiny dust particles has engulfed much of Mars over the last two weeks and prompted NASA’s Opportunity rover to suspend science operations. But across the planet, NASA’s Curiosity rover, which has been studying Martian soil at Gale Crater, is expected to remain largely unaffected by the dust. While Opportunity is powered by sunlight, which is blotted out by dust at its current location, Curiosity has a nuclear-powered battery that runs day and night.

The Martian dust storm has grown in size and is now officially a “planet-encircling” (or “global”) dust event.

Mars Needs Women — NASA Needs Everybody

In the 1967 film, Mars Needs Women, a team of martians invades Earth to kidnap women to help repopulate their dying species. Shot over two weeks on a minuscule budget and padded out with stock footage, the movie obtained cult status as one of those cinematic disasters that was so bad it was unintentionally hilarious.

A half century later, NASA finds itself in a not entirely dissimilar situation. Only this problem is not nearly as funny.

The space agency lacks sufficient personnel with the proper skill sets to undertake its complex missions to the moon, Mars and beyond. A number of key programs have been affected by the shortfall already.

NASA’s workforce is also aging. More than half the agency’s employees are 50 years and older, with one-fifth  currently eligible for retirement. Finding replacement workers with the right mix of skills is not always easy as NASA faces increased competition from a growing commercial space sector.

The space agency is addressing these challenges, but it’s too early to tell how successful these efforts will be, according to a new Government Accountability Office (GAO) assessment.

HUNTINGTON BEACH, Calif. (NASA PR) — A host of CubeSats, or small satellites, are undergoing the final stages of processing at Rocket Lab USA’s facility in Huntington Beach, California, for NASA’s first mission dedicated solely to spacecraft of their size. This will be the first launch under the agency’s new Venture Class Launch Services.

Scientists, including those from NASA and various universities, began arriving at the facility in early April with spacecraft small enough to be a carry-on to be prepared for launch.

A team from NASA’s Goddard Spaceflight Center in Greenbelt, Maryland, completed final checkouts of a CubeSat called the Compact Radiation Belt Explorer (CeREs), before placing the satellite into a dispenser to hold the spacecraft during launch inside the payload fairing. Among its missions, the satellite will examine the radiation belt and how electrons are energized and lost, particularly during events called microbursts — when sudden swarms of electrons stream into the atmosphere.

This facility is the final stop for designers and builders of the CubeSats, but the journey will continue for the spacecraft. Rocket Lab will soon ship the satellites to New Zealand for launch aboard the company’s Electron orbital rocket on the Mahia Peninsula this summer.

The CubeSats will be flown on an Educational Launch of Nanosatellites (ELaNa) mission to space through NASA’s CubeSat Launch Initiative. CeREs is one of the 10 ELaNa CubeSats scheduled to be a part of this mission.
