The report is delayed by a day or so (communications delay? non-essential data delay?), but it’s still really cool to see what the temperature, wind speed, and barometric pressure is at Elysium Planitia.
I’d just like to note for the record that at some point on Monday, it was actually warmer on Mars than it is right now in Vermont. ♫ Gotta get up, gotta get out, gotta get out into the Martian sun… ♫
NASA’s InSight mission recently landed on Mars and like other missions before it, the lander is a equipped with a camera and has sent back some pictures of the red planet. But InSight is also carrying a couple of instruments that made it possible to record something no human has ever experienced: what Mars sounds like:
Two very sensitive sensors on the spacecraft detected these wind vibrations: an air pressure sensor inside the lander and a seismometer sitting on the lander’s deck, awaiting deployment by InSight’s robotic arm. The two instruments recorded the wind noise in different ways. The air pressure sensor, part of the Auxiliary Payload Sensor Subsystem (APSS), which will collect meteorological data, recorded these air vibrations directly. The seismometer recorded lander vibrations caused by the wind moving over the spacecraft’s solar panels, which are each 7 feet (2.2 meters) in diameter and stick out from the sides of the lander like a giant pair of ears.
The sounds are best heard with a good pair of headphones.
After a seven-month journey covering over 300 million miles, NASA’s InSight probe will land on the surface of Mars today around 3pm. The video embedded above is a live stream of mission control at NASA’s Jet Propulsion Laboratory that starts at 2pm and will be the best thing to watch as the probe lands. (See also this live stream of NASA TV.) The landing will occur around 2:47pm ET but the landing signal from Mars won’t arrive on Earth until 2:54pm ET at the earliest. And no video from the landing itself of course…”live” is a bit of a misnomer here but it still should be exciting.
NASA produced this short video that shows what’s involved in the landing process, aka how the probe goes from doing 13,000 mph to resting on the surface in just six-and-a-half minutes.
NASA’s study of Mars has focused on the planet’s surface and the possibility of life early in its history. By contrast, the InSight mission — the name is a compression of Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport — will study the mysteries of the planet’s deep interior, aiming to answer geophysical questions about its structure, composition and how it formed.
I love this stuff…the kids and I will be watching for sure!
