NASA’s InSight successfully lands on Mars
The unmanned lander will help scientists learn more about the interior of Mars and the development of rocky planets.
- The unmanned spacecraft touched down on Mars without problems shortly before 3 p.m. ET on Monday.
- It was a precarious landing that NASA engineers had described as "seven minutes of terror."
- InSight will study the interior of Mars, and could help scientists discover the presence of liquid water on the red planet.
NASA's InSight—a robotic lander designed to study the interior of rocky planets—successfully landed on Mars Monday afternoon, marking the agency's eighth successful deployment of a spacecraft on the red planet.
It was a precarious landing process that NASA engineers predicted would be "seven minutes of terror."
"This vehicle is very, very complicated," Rob Grover, InSight's entry, descent and landing (EDL) lead, during a NASA live stream on Monday. "It uses 12 engines, each of those engines are pulsed 10 times a second, producing these little tiny impulses, almost like little bullets that keep the vehicle going at a constant velocity as it approaches the ground."
Grover said the agency had to rely on an algorithm to guide the unmanned lander to the surface.
"We can't joystick the landing, so we have to rely on the commands we pre-program into the spacecraft. We've spent years testing our plans, learning from other Mars landings and studying all the conditions Mars can throw at us," Grover said in a recent statement.
The practice paid off. A few minutes before 3 p.m., the mission control room erupted in cheers as "touchdown confirmed!" played over the speakers.
"This is what we really hoped and imagined in our mind's eye," Grover said, adding that engineers still have to check the data to confirm how smoothly the landing really was.
After making the 300-million-mile voyage from Earth, InSight landed at a site called Elysium Planitia, a flat plain on Mars's equator about 370 miles from where Curiosity touched down in August 2012. The mission, led by NASA's Jet Propulsion Laboratory, aims is to help scientists learn more about the early development of rocky planets, and possibly discover the presence of liquid water on Mars.
"The lander uses cutting edge instruments, to delve deep beneath the surface and seek the fingerprints of the processes that formed the terrestrial planets," NASA wrote on its website. "It does so by measuring the planet's "vital signs": its "pulse" (seismology), "temperature" (heat flow), and "reflexes" (precision tracking)."
InSight was followed to Mars by two tiny experimental satellites, dubbed CubeSats, whose primary purpose was to relay radio transmissions from the lander back to Earth. NASA officials said it would take months before they start obtaining the "best data" from InSight.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Elon Musk took issue with recent ideas for space exploration from Jeff Bezos.
- Elon Musk and Jeff Bezos have sparred over space exploration previously.
- Musk wants to focus on Mars while Bezos has the moon and space colonies as goals.
- In a recent tweet, Musk called out Bezos's plans for space colonies as unrealistic.
If you don't want to know anything about your death, consider this your spoiler warning.
- For centuries cultures have personified death to give this terrifying mystery a familiar face.
- Modern science has demystified death by divulging its biological processes, yet many questions remain.
- Studying death is not meant to be a morbid reminder of a cruel fate, but a way to improve the lives of the living.
- Push Past Negative Self-Talk: Give Yourself the Proper Fuel to Attack the World, with David Goggins, Former NAVY SealIf you've ever spent 5 minutes trying to meditate, you know something most people don't realize: that our minds are filled, much of the time, with negative nonsense. Messaging from TV, from the news, from advertising, and from difficult daily interactions pulls us mentally in every direction, insisting that we focus on or worry about this or that. To start from a place of strength and stability, you need to quiet your mind and gain control. For former NAVY Seal David Goggins, this begins with recognizing all the negative self-messaging and committing to quieting the mind. It continues with replacing the negative thoughts with positive ones.
