These are the stories of the scientists featured in the Lego Women of Nasa set: Nancy Grace Roman, Margaret Hamilton, Sally Ride and Mae Jemison.

Nasa has estimated the impact of atmospheric rivers on global climate, including rain, floods and droughts.

Camera technology has grown rapidly over the last decade and Nasa intends to make full use of it by equipping its next rover with high-quality imaging gear.

The surface of Mars suggests that it was moved around and formed by flowing water, but there has never been enough water on the planet to do this.

Nasa's Juno mission has been hard at work collecting data for scientists to study. Here are a few revelations that Juno has made over the last few months.

There are several observatories and space missions that are dedicated to observing the sun and studying space weather.

Ceres is the largest rock in the asteroid belt and one of the candidates for finding life in the solar system.

The December mission will mark the first flight from the refurbished launch pad SLC-40 since the explosion.

Sand dunes on Hellas Planitia have large, linear scratch marks on its sides at high latitudes.

The space probe will manoeuvre itself into a new orbit which is closer to Ceres' surface in order to get new insights about the dwarf planet.

Scientists studying Cassini's data have found that Titan's atmosphere has several toxic cloud formations containing hydrogen cyanide and benzene over its South Pole.

Nasa found that heat and droughts in the tropical regions of Africa, Indonesia and South America are responsible for the surge in the release of atmospheric CO2.

Following Cassini, Nasa needs a new mission to look for life on Saturn's mysterious moons.

The X3 is a Hall thruster, a type of ion thruster that creates propulsion by firing a stream of electrically charged atoms, called plasma, out of a nozzle.

A breakthrough in the research, scientists believe, would help prevent humanitarian disasters and false alarms.

The participants must remain in the same position for entire duration of the Nasa study, which causes their bodies to adapt as if they were in space.

An object known as TC4 came within 26,000 miles of the planet's surface - which is inside the moon's orbit and just above the altitude of satellites which orbit the Earth

Nasa's Space Launch System will have the largest and most powerful rocket stage ever assembled and will aid in deep space exploration, including missions to Mars.

Nasa wants to integrate the unmanned aerial system with the national airspace system so that drones and commercial flights can share airspace.

A bird crossed the Sun at the exact same time as the ISS, which was flying past at over 28,000kms per hour.

Triton is the largest of Neptune's 13 moons and Nasa says that is has not been studied in 16 years. Nasa is using its flying observatory Sofia for this mission.

Vice President Mike Pence has said that the Trump administration is intent on sending Americans to the Moon.

Orbiting space station would allow astronauts carry out explorations of the Red Planet.

The skyscraper-sized formations are made entirely of methane, says Nasa.

The US space agency said it wanted to expand human presence into the solar system.

Planetary gravity maps developed by Nasa can be used to find the density of any rocky planet.

The tunnels - known as lava tubes - could even help in the search for alien life on Mars.

European Space Agency astronaut Paolo Nespoli captured the astonishing footage of the Northern Lights.

The melt occurred despite having summer conditions that were not unusual.

Scientists have discovered huge deposits of ice on the closest planet to the Sun.
