Pasadena, CA – “Tango delta. Touchdown confirmed. Perseverance safely on the surface of Mars, ready to begin seeking the signs of past life.” For more than six years, the Mars Entry, Descent, and Landing Instrumentation 2 (MEDLI2) team waited to hear these words.
NASA’s Perseverance rover successfully landed on February 18th, 2021, beginning its robotic exploration of the Red Planet. MEDLI2 was one of the crucial technologies on the rover’s protective aeroshell that helped document the entry, descent, and landing (EDL) of the spacecraft. All of the MEDLI2 data was stored on Perseverance for transmission to Earth after a successful landing.
Washington, D.C. – NASA and Boeing have completed Starliner’s last parachute balloon drop test ending a reliability campaign that will help strengthen the spacecraft’s landing system ahead of crewed flights to and from the International Space Station.
The campaign, developed by both Boeing and NASA, used six balloon drop tests of a Starliner test article to gather supplemental performance data on the spacecraft’s parachutes and landing system. Each drop test focused on a different set of adverse conditions and used pre-flown parachutes to evaluate reusability margins for future missions.
Washington, D.C. – Mars is an obvious source of inspiration for science fiction stories. It is familiar and well-studied, yet different and far enough away to compel otherworldly adventures. NASA has its sights on the Red Planet for many of the same reasons.
Greenbelt, MD – When Solar Orbiter launches on its journey to the Sun, there’s one key piece of engineering making this ESA-NASA mission possible: the heat shield.
Seeking a view of the Sun’s north and south poles, Solar Orbiter will journey out of the ecliptic plane — the belt of space, roughly in line with the Sun’s equator, through which the planets orbit. Slinging repeatedly past Venus in order to draw near the Sun and climb higher above the ecliptic, the spacecraft bounds from the Sun and back toward the orbit of Earth throughout its mission.
Washington, D.C. – NASA says when a spacecraft built for humans ventures into deep space, it requires an array of features to keep it and a crew inside safe. Both distance and duration demand that spacecraft must have systems that can reliably operate far from home, be capable of keeping astronauts alive in case of emergencies and still be light enough that a rocket can launch it.

Pasadena, CA – On November 26th, 2018 NASA’s InSight mission knew the spacecraft touched down within an 81-mile-long (130-kilometer-long) landing ellipse on Mars. Now, the team has pinpointed InSight’s exact location using images from HiRISE, a powerful camera onboard another NASA spacecraft, Mars Reconnaissance Orbiter (MRO).
The InSight lander, its heat shield and parachute were spotted by HiRISE (which stands for High Resolution Imaging Science Experiment), which is onboard NASA’s Mars Reconnaissance Orbiter, in one set of images last week on December 6th, and again on Tuesday, December 11th.

Pasadena, CA – NASA says that every Mars landing is a knuckle-whitening feat of engineering. But each attempt has its own quirks based on where a spacecraft is going and what kind of science the mission intends to gather.
On November 26th, 2018 NASA will try to safely set a new spacecraft on Mars. InSight is a lander dedicated to studying the deep interior of the planet – the first mission ever to do so.

Greenbelt, MD – Early on an August morning, the sky near Cape Canaveral, Florida, will light up with the launch of Parker Solar Probe. No earlier than August 6th, 2018, a United Launch Alliance Delta IV Heavy will thunder to space carrying the car-sized spacecraft, which will study the Sun closer than any human-made object ever has.
On July 20th, 2018, Nicky Fox, Parker Solar Probe’s project scientist at the Johns Hopkins University Applied Physics Lab in Laurel, Maryland, and Alex Young, associate director for science in the Heliophysics Science Division at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, introduced Parker Solar Probe’s science goals and the technology behind them at a televised press conference from NASA’s Kennedy Space Center in Cape Canaveral, Florida.

Washington, D.C. – One key to understanding what keeps the spacecraft and its instruments safe, is understanding the concept of heat versus temperature. Counterintuitively, high temperatures do not always translate to actually heating another object.
In space, the temperature can be thousands of degrees without providing significant heat to a given object or feeling hot. Why? Temperature measures how fast particles are moving, whereas heat measures the total amount of energy that they transfer. Particles may be moving fast (high temperature), but if there are very few of them, they won’t transfer much energy (low heat).
