Nasa cancels all-female spacewalk, citing lack of suit in woman's size

Nasa's plans for an all-female spacewalk have fallen through - at least in part because the agency doesn't have enough spacesuits that fit the astronauts.

Early this month, Nasa announced that Christina Koch and Anne McClain would take part in the first-of-its kind mission on 29 March, walking outside the international space station (ISS) to install new batteries. In the past, missions have been all-male or male-female.

But in a press release on Monday, Nasa said its plans had changed, "in part" due to a shortage of outerwear. McClain had "learned during her first spacewalk that a medium-size hard upper torso - essentially the shirt of the spacesuit - fits her best." Only one such top can be made by Friday, the agency said, and it will go to Koch.

When McClain took part in a spacewalk last week, she became the 13th woman to do so, Nasa says; Koch will be the 14th. McClain is now "tentatively scheduled" to perform her next one on 8 April.

McClain is sharing both ISS missions with men.

The first woman to perform a spacewalk was the Soviet cosmonaut Svetlana Savitskaya, 35 years ago. More than 500 people have been into space, but only 11% have been women, Reuters reported. But Koch and McClain were both part of Nasa's 2013 class, which was half female.

Fitting for spacesuits is a tricky business, according to, since microgravity makes you taller. McClain tweeted this month that she was 2in taller than when she launched.

Material from one of the stars is regularly spewing out, being drawn in by the gravity of its companion star and filling the gap between both stellar bodies. The material is pushed out into space in a shape that...

'Marsquake' detected for first time, Nasa says

Nasa has detected a probable "Marsquake" for the first time. The suspected seismic event on the Red Planet was recorded using silicon sensors developed in the UK. A dome-shaped apparatus known as Seismic Experiment for Interior Structure [SEIS] landed on Mars last year equipped with the sensors, which were built with £4 million in funding from the UK Space Agency Nasa said the measuring of the quake, which occurred on April 6, marked the "birth of a new discipline - Martian seismology". Chris Skidmore, the science minister, said it was a "testament to the UK's world leading science and engineering space sector". Professor Tom Pike of Imperial College London,...

NASA's robotic probe InSight has detected and measured what scientists believe to be a "marsquake," marking the first time a likely seismological tremor has been recorded on another planet, the Jet Propulsion Laboratory in California reported on Tuesday. The breakthrough came five months after InSight, the first spacecraft designed specifically to study the deep interior of a distant world, touched down on the surface of Mars to begin its two-year seismological mission on the red planet. The faint rumble characterized by JPL scientists as a likely marsquake was recorded on April 6, the lander's 128th Martian day, or sol.
