NASA astronauts go spacewalking days after reaching orbit

CAPE CANAVERAL, Florida: Two new arrivals at the International Space Station went spacewalking Thursday less than a week after moving in.
NASA astronauts Drew Feustel and Ricky Arnold quickly set about installing new wireless antennas, replacing a failed camera and removing jumper hoses from a leaky radiator.
Mission Control said the spacewalkers would complete the chores despite a late start due to spacesuit trouble. Feustel’s suit failed three leak checks after he put it on, but passed on the fourth try. That put the astronauts more than an hour late in getting outside.
“You guys are working harder up there today than in the gym,” Mission Control said even before the spacewalk had begun.
Feustel and Arnold rocketed away from Kazakhstan last Wednesday and arrived at the 250-mile-high outpost two days later. They will remain on board until August. Shuttle astronauts often went spacewalking a few days after reaching orbit, given their short flights, but it’s less common for station residents who spend five to six months aloft.
A space station manager, NASA’s Kenny Todd, said earlier this week that both Feustel and Arnold were experienced spacewalkers from the old space shuttle days and were used to a quick transition in orbit. But Todd cautioned there’s nothing routine about spacewalking and is probably the most dangerous undertaking by orbiting astronauts.
This was Feustel’s seventh spacewalk and Arnold’s third.
“Welcome to the vacuum of space ... welcome back,” said Mission Control.
The intense pace continues next week. SpaceX plans to launch a load of supplies to the station crew Monday from Cape Canaveral, Florida.


Japan to trial ‘world’s first urine test’ to spot cancer

Japan to trial ‘world’s first urine test’ to spot cancer

  • Previous research has shown a new blood test has potential to detect eight different kinds of tumors before they spread
  • The research starts in April and will run until September

TOKYO: A Japanese firm is poised to carry out what it hailed as the world’s first experiment to test for cancer using urine samples, which would greatly facilitate screening for the deadly disease.
Engineering and IT conglomerate Hitachi developed the basic technology to detect breast or colon cancer from urine samples two years ago.
It will now begin testing the method using some 250 urine samples, to see if samples at room temperature are suitable for analysis, Hitachi spokesman Chiharu Odaira told AFP.
“If this method is put to practical use, it will be a lot easier for people to get a cancer test, as there will be no need to go to a medical organization for a blood test,” he said.
It is also intended to be used to detect paediatric cancers.
“That will be especially beneficial in testing for small children” who are often afraid of needles, added Odaira.
Research published earlier this year demonstrated that a new blood test has shown promise toward detecting eight different kinds of tumors before they spread elsewhere in the body.
Usual diagnostic methods for breast cancer consist of a mammogram followed by a biopsy if a risk is detected.
For colon cancer, screening is generally conducted via a stool test and a colonoscopy for patients at high risk.
The Hitachi technology centers around detecting waste materials inside urine samples that act as a “biomarker” — a naturally occurring substance by which a particular disease can be identified, the company said in a statement.
The procedure aims to improve the early detection of cancer, saving lives and reducing the medical and social cost to the country, Odaira explained.
The experiment will start this month until through September in cooperation with Nagoya University in central Japan.
“We aim to put the technology in use in the 2020s, although this depends on various things such as getting approval from the authorities,” Odaira said.
