Rocket engine exhaust pollution extends high into Earth's atmosphere
Wednesday, 18 May 2022 04:39
Reusable space technology has led to a rise in space transportation at a lower cost, as popularized by commercial spaceflights of companies like SpaceX and Virgin Galactic. What is poorly understood, however, is rockets' propulsion emissions creating significant heating and compositional changes in the atmosphere.

Curiosity continues to navigate challenging terrain. The drive executed over the weekend moved us 8 m from our previous location. Prior to the weekend drive, we completed contact science with APXS and MAHLI on targets "Pedra Pintada" and "San Pedro," the latter of which was brushed with the Dust Removal Tool (DRT) to remove thin airfall dust that was coating the surface of the rock face. Dust is Mars' emitted energy and seasonal energy imbalance

A seasonal imbalance in the amount of solar energy absorbed and released by the planet Mars is a likely cause of the dust storms that have long intrigued observers, a team of researchers reports.
Mars' extreme imbalance in energy budget (a term referring to the measurement of solar energy a planet takes in from the sun then releases as heat) was documented by University of Houston research Seeing through the fog-pinpointing young stars and their protoplanetary disks

Imagine walking through a dense, hazy fog in the middle of the night, seeing patches of light from cars and towns shimmering in the distance. It's nearly impossible to tell if the lights are deep in the fog or beyond it. Astronomers trying to find young stars face a similar problem: the light from stars they're hunting is shimmering through great big regions of hazy gas and dust in space, called DARPA pursues tactical-grade clock that maintains precision over time

Mission success can come down to mere millionths or billionths of a second and current military systems that rely on global positioning system (GPS) timing updates are inherently vulnerable. Though GPS is a revolutionary capability, it is unreliable underground or underwater and can be degraded or unavailable due to adversarial signal jamming.

NASA's InSight still hunting marsquakes as power levels diminish
Tuesday, 17 May 2022 20:35
Dusty solar panels and darker skies are expected to bring the Mars lander mission to a close around the end of this year.
NASA's InSight Mars lander is gradually losing power and is anticipated to end science operations later this summer. By December, InSight's team expects the lander to have become inoperative, concluding a mission that has thus far detected more than 1,300 marsquakes—most recently, a magnitude 5 that occurred on May 4—and located quake-prone regions of the Red Planet.
The information gathered from those quakes has allowed scientists to measure the depth and composition of Mars' crust, mantle, and core. Additionally, InSight (short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) has recorded invaluable weather data and studied remnants of Mars' ancient magnetic field.

NASA's InSight lander: The lonely fate of a robot on Mars
Tuesday, 17 May 2022 17:48
Covered in the red dust that sealed its fate, the NASA InSight lander is slowly shutting down, more than 250 million kilometers from home.
With its solar panels now obscured by the red planet's debris, the four-year-old robot is running out of power. One by one, its instruments are being taken offline: its robotic arm moving into "retirement pose," its seismometer likely to be turned off sometime in June.
Dr. Catherine Johnson, co-investigator on the InSight science team and professor in the department of earth, ocean and atmospheric sciences, discusses what the team discovered, what questions are left to answer, and just what will happen to the little lander that could.
What was the lander's mission and what did it find?
