NASA's robotic rover Curiosity is making its mark on Mars - leaving tracks that are big enough to be seen from space.
NASA's Mars rover Curiosity beamed Will.i.am's new song, Reach for the Stars, to earth.
The Black Eyed Peas rapper will debut his latest single Reach For The Stars on Mars tonight.
NASA has tweeted this photograph of the team behind the Curiosity Mars mission visiting the set of the hit US TV comedy show The Big Bang Theory, which is based around four post-graduate scientists.
One of the NASA scientists giving an update on the Mars mission this evening said that everything on the Curiosity rover is working well and that the main challenge is "dampening excitement" so that the staff working on the mission get some rest.
NASA has released this image of the Curiosity rover's first track marks on the surface of Mars.
Curiosity is now about 6 metres (20 feet) from where it touched down.
The Curiosity rover has tweeted a photograph of the spot where it landed on Mars, which NASA said today has been named 'Bradbury Landing' after the author Ray Bradbury.
This is the first laser spectrum from the 'Chemistry and Camera' (ChemCam) instrument on NASA's Curiosity rover.
Graphs like this are created when the rover zaps a rocks with its laser and uses spectrometers to analyse the gases that are emitted and detect different elements present in the rock.
The Mars rover has zapped several rocks in order to test its laser systems are working.
The first rock, dubbed 'Coronation', was chosen because of its proximity. Other choices include an outcrop of rocks that were uncovered by the Sky Crane thrusters during the landing.
NASA scientists are looking forward to doing "lots more science with the ChemCam instrument".
The Curiosity rover's drive system is working well, NASA has announced after several tests.
These included going forward about 4.5 metres (15 feet), rotating 120 degrees and then reversing about 2.5 metres (8 feet).
The mission's lead rover driver, Matt Heverly, said: "We have a fully functioning mobility system with lots of amazing exploration ahead."
Its first drive is scheduled for early September.
NASA has announced that the spot where the Curiosity rover touched down will be named 'Bradbury Landing' after the author Ray Bradbury whose 1950 short story 'The Martian Chronicles' imagined humans colonising Mars.
Mr Bradbury was born 92 years ago today and died earlier this year.
Michael Meyer, NASA program scientist for Curiosity, said: "Many of us and millions of other readers were inspired in our lives by stories Ray Bradbury wrote to dream of the possibility of life on Mars."
NASA is giving a press conference about its Curiosity mission on Mars.
Its scientists report that the mission is going extremely well and is running ahead of schedule.
