The cubesats, intended primarily as technology demonstrations, were created to provide a realtime relay of telemetry from InSight during landing, without which it would have been hours before controllers knew if the spacecraft had landed successfully.
Monday afternoon's touchdown was preceded by a series of complicated maneuvers as InSight made its way through Mars' atmosphere.
The internet fell in love immediately. Project manager Tom Hoffman said the spacecraft landed close to the bull's-eye, but NASA did not have yet have the final calculations.
"It is wonderful news that the InSight spacecraft has landed safely on Mars", said Sue Horne, head of space exploration at the UK Space Agency. A third experiment, the Rotation and Interior Structure Experiment or RISE, sits on the lander itself and will monitor the position of Mars' North Pole to determine how much the planet is wobbling.
NASA went with its old, straightforward approach this time, using a parachute and braking engines to get InSight's speed from 12,300 mph when it pierced the Martian atmosphere, about 77 miles up, to 5 mph at touchdown.
By examining the interior of Mars, scientists hope to understand how our solar system's rocky planets formed 4.5 billion years ago and why they turned out so different - Mars cold and dry, Venus and Mercury burning hot, and Earth hospitable to life.
Once on Mars, InSight will drill into the ground with a probe to offer mankind a first-ever look inside the Red Planet.
NASA's science chief, Thomas Zurbuchen said previously: "As humanity, as explorers - we're batting at less than 50 percent".
The probe, which took a six-month journey beginning with a California launch, has delivered three new instruments to the surface of Mars. Although InSight will also have an onboard weather station and suite of cameras, the mission's focus is on peeling back the profound mysteries of the Martian interior. It will take months to set up and fine-tune the instruments, and lead scientist Bruce Banerdt said he doesn't expect to start getting a stream of solid data until late next spring.
Until now, all Mars missions have focused on the planet's surface and atmosphere.
Unlike earthquakes, marsquakes are a outcome of a cooling and shrinking world, says Hoffman, and hopes are high that there will be many marsquakes for InSight to detect. Being completely solar-powered, this is an important activity that ensures the lander has all the power it needs. NASA's Mars Odyssey will then fly overhead to confirm that the panels are out. "That's why scientists chose Elysium Planitia as InSight's home".
The MarCO-A cubesat also indirectly performed science during the flyby as its radio signals were occluded by the planet as it passed behind Mars. The self-hammering mole will burrow five metres down to measure the planet's internal heat, while the seismometer listens for possible quakes.
This year's blizzard is the worst storm to hit Chicago since November 25-26, 1975, which dumped 8.9 inches on the Windy City. Kansas City International Airport shut down on Sunday afternoon as crews battled to clear the runway and de-ice planes.
An armed separatist group that opposes China's economic presence in Pakistan has claimed responsibility for the attack. Chinese nationals in Karachi generally consider it a safe city to move around, carrying out their day-to-day business.
A point was cut from me in the final round, but there was a lot of closing, pulling and pushing from both of us. Taller boxers can have the advantage due to their reach, they can get inside immediately and come back again.
His tweet came as the Mexican government reportedly said it would deport migrants who tried storming the USA border on Sunday. He said he understands that the migrants want to be part of the United States, "but there's a legal way to do it".
OPEC and other nations agreed to hike output in June based in part on Trump's vows to strictly enforce the sanctions. Natural gas futures have surged about 40 percent over the last month on colder-than-average weather.
President Trump speaks to members of the military over the phone Thursday from his Mar-a-Lago resort in Palm Beach, Fla . Indeed, asked what he was thankful for this Thanksgiving , Trump cited his "great family", as well as himself.
"The 30-year-old is accused of sexually assaulting a woman in Hunter Valley, north of Sydney, on 30 September". The serious nature of the charges mean Hayne must show cause why his detention in custody is not justified.
Another clip saw her singing with a group of guests, along with the caption: "Every time a new girl arrives we sing them home". Winfrey spent much of her childhood traveling between the homes of her mother and father, Vernon Lee.
The statement was more like a series of Trump's tweets , very far from the White House standards that we are familiar with. Trump has refused to listen to audio of the killing. "They said he might have done it".
It is unclear whether Mueller will be satisfied with the written answers or will still seek to question the president in person. Mueller could theoretically still try to subpoena the president if he feels the answers are not satisfactory.
Bus attack postpones South American soccer final
The South American Football Federation (CONMEBOL) initially delayed the kick-off twice, before deciding to postpone. Unsurprisingly, it soon became clear that the final would not be going ahead on time on Saturday night.
Federal Agencies Issue Dire Climate Change Warning
Lindsay Walters, a spokesman for the White House , said the new report was "largely based on the most extreme scenario". Communities also need to advance measures to adapt to the challenges of a changing climate.
Steph Curry’s Porsche hit twice in 10 minutes on highway
He instead received treatment on his groin injury, which will rule him out of Friday's game against the Portland Trail Blazers. He was on his way to the team's shoot-around when he was involved in the three-car crash before 9 a.m. on Highway 24.
Warriors skid to 4th straight loss vs Thunder
He was carted off on a stretcher with 7:17 left after crashing to the floor and colliding with Warriors forward Jonas Jerebko . Clearly in pain, Diallo moved himself off the court and was under basket for several minutes.
