In case you were curious, here is what an alien sees before he/she/it goes to sleep.

NASA’s Curiosity Mars rover captured the above image on April 15, and it’s being described as the first sunset observed in color by the spacecraft.

The photos were taken last month, but they were just sent back to Earth last week.

While Mars may appear red, the sunset is actually blue, and the Jet Propulsion Laboratory explains why this is possible:

Dust in the Martian atmosphere has fine particles that permit blue light to penetrate the atmosphere more efficiently than longer-wavelength colors. That causes the blue colors in the mixed light coming from the sun to stay closer to sun’s part of the sky, compared to the wider scattering of yellow and red colors. The effect is most pronounced near sunset, when light from the sun passes through a longer path in the atmosphere than it does at mid-day.

Curiosity first landed on Mars’s Gale Crater in August 2012 with a mission of determining whether or not Mars is or ever was habitable by life forms.

Here’s an animated GIF of the sunset, which uses a series of photos takes over a period of about 6 minutes, 51 seconds. The sight apprently inspired the rover to recite some lines from T.S. Eliot’s “The Love Song of J. Alfred Prufrock” on its Twitter account.

"Once proven, solar sail technology could enable a host of versatile space missions, including flying an advanced space-weather warning system to more quickly and accurately alert satellite operators and utilities on Earth of geomagnetic storms caused by coronal mass ejections from the sun," NASA said in a release.

In an effort to emphasize how goddamn tiny we are relative to the rest of the universe, NASA released this composite image of the night sky to the public. Composed of more than a billion stars and 2.7 million images, it serves as a constant reminder of how little of the universe we've explored. Short version: Fund NASA please.

Newman is best known for research on form-fitting spacesuits that use mechanical counterpressure to provide greater freedom of motion for astronauts than conventional suits. "Ultimately, the big advantage is mobility, and a very lightweight suit for planetary exploration," Newman said in a Sept. 18 press release from MIT about her group's research.

She has also been involved in science and technology policy. She has a master's degree in technology and policy from MIT and since 2003 has served as director of its Technology and Policy Program.

The solar-electric propulsion thruster pictured above ditches burning chemical fuel for xenon ions accelerated by an electric field generated using solar panels. This provides a steady stream of ions that can slowly nudge a spacecraft to high speeds with minimal fuel, making it a good choice for long-range missions.

NASA's Lunar Laser Communication Demonstration (LLCD) has made history using a pulsed laser beam to transmit data over the 239,000 miles between the moon and Earth at a record-breaking download rate of 622 megabits per second (Mbps).

LLCD is NASA's first system for two-way communication using a laser instead of radio waves. It also has demonstrated an error-free data upload rate of 20 Mbps transmitted from the primary ground station in New Mexico to the spacecraft currently orbiting the moon.

R2, which has been on the ISS since 2011, has a mission: clean handrails, vacuum air filters and take air-flow measurements. The problem is it doesn't yet have the ability to learn and complete the work. So NASA is looking for someone to teach the bot. The Robonaut Challenge calls on contestants to write algorithms that allow R2 to interact with a training dashboard the space agency built.

NASA has hired artist Ted Southern and his company Final Frontier Designs to design lightweight, cost-effective spacesuits for civilian travelers. Previously to this, Ted’s most high-profile work was probably the elaborate, glitter-covered wings you ignore during theVictoria’s Secret fashion show. He’s also designed costumes for Cirque du Soleil and Broadway. So yes, space is about to get fabulous.
