Signals from Mars will take 8 minutes to travel to Earth on Monday. By the time we hear that InSight has reached the top of Mars' atmosphere, the lander will have already touched down safely ... or crashed.

On November 26, 2018, NASA’s InSight lander will make its daring descent to Mars' surface. NASA engineers hope to broadcast word of a successful touchdown at 20:00 UTC (3 p.m. EST), with live landing commentary starting about an hour before.

"If you were a Martian coming to explore Earth's interior, it wouldn't matter if you put down in the middle of Kansas or the beaches of Oahu ... The beauty of this mission is happening below the surface."

Last week, the space technology startup Lunar Outpost publicly displayed its rover concept - the Lunar Resource Prospector - for the 1st time. The rovers may help pave the way for a human return to the moon.

"We're returning to the moon, preparing to go beyond to Mars. We are going. We are NASA."

It hasn't been easy for astronomers to peer into the cores of merging galaxies. Dust obscures the view. Now, new research has given astronomers a better look.

Gaia satellite data revealed the galaxy, which has avoided detection until now, thanks to its extremely low density and hiding place behind the shroud of the Milky Way’s disk.

Activity on the sun’s surface creates the conditions known as space weather, that can, at its worst, damage Earth satellites and cause electrical blackouts.

Astronomers are "99 percent confident" that this exoplanet is real and not a false detection. The planet for Barnard's star - 2nd closest star system to our sun - appears to be a cold super-Earth.

First, asteroids can serve as pit stops - and provide resources - for future space exploration. Second, some asteroids or comets may be hazards to Earth.
