NASA is counting down to a nail-biting touchdown on Monday of the US$993 million Mars InSight, the first spacecraft to listen for quakes and study the inner workings of another rocky planet.
No one is on board the spacecraft, which launched nearly seven months ago and has traveled about 482 million kilometers, but part of its mission is to inform efforts to one day send human explorers to the Red Planet, which NASA hopes to do by the 2030s.
The lander is the first to reach Mars since 2012, when NASA’s Curiosity rover touched down to scour the surface and analyze rocks for signs that life forms could once have inhabited Earth’s neighbor, now a frigid and dry planet.

InSight must survive tense entry into Mars’ atmosphere, traveling at 19,800kph and swiftly slowing to just 8kph.
This entry, descent and landing phase begins at 11:47 am in California, and is only half-jokingly referred to at NASA as the “six-and-a-half minutes of terror.”
Of 43 missions launched toward Mars, only 18 have made it intact — a success rate of about 40 percent. All those that made it came from the US.
“Going to Mars is really, really hard,” NASA Science Mission Directorate associate administrator Thomas Zurbuchen said. “The exciting part is we are building on the success of the best team that has ever landed on this planet, which is the NASA team with its contractors and its collaborators.”
The name InSight is derived from “Interior Exploration using Seismic Investigations, Geodesy and Heat Transport.”
The spacecraft itself stands about waist high, at 1m, and if its solar arrays are deployed they will span 6m.
Fully fueled, InSight weighs more than 360kg, about the same as a Harley Davidson motorcycle.
Its central instrument is a quake-sensing seismometer that was made by French space agency CNES.
“This is the only NASA mission until now which is conceived around a foreign-made instrument,” CNES president Jean-Yves le Gall said. “So it’s a mission that is fundamentally for the United States, for France and for improving our understanding of Mars.”
The six quake sensors on board are so sensitive that they should reveal the smallest tremors on Mars, such as the faint pull of its moon Phobos, impacts from meteors and possibly evidence of volcanic activity.
Seismology has taught humanity much about the formation of Earth about 4.5 billion years ago, but much of the Earth-based evidence has been lost to the recycling of the crust, driven by plate tectonics. This process does not exist on Mars.
The spacecraft also has a self-hammering probe that can burrow as deep as 3m to 5m, offering the first precise measurement of below-ground temperatures on Mars and how much heat escapes from its interior.
InSight was built by Lockheed Martin, and is modeled after the Phoenix spacecraft that landed near the Martian north pole in 2008. Like Phoenix, InSight’s arrival is to be aided by a parachute. It has a heat shield to help slow down the spacecraft and protect against the hot friction of entering Mars’ atmosphere.
The lander must set itself down upright. Then, another critical step is for the solar arrays to deploy, as the lander is to rely entirely on solar power for its one-year mission.
NASA should know within minutes if the landing went well or not, but will have to wait more than five hours for confirmation of the solar array deployment, due to the orbit pattern of the Mars Reconnaissance Orbiter and Mars Odyssey, which can communicate InSight’s status back to Earth.
That first confirming ping should be at 8:04pm GMT.
“I do have a lot of blood sweat and tears invested in this, and I am looking forward to a nice, safe touchdown on Monday,” said Stu Spath, InSight program manager at Lockheed Martin.
A fire caused by a burst gas pipe yesterday spread to several homes and sent a fireball soaring into the sky outside Malaysia’s largest city, injuring more than 100 people. The towering inferno near a gas station in Putra Heights outside Kuala Lumpur was visible for kilometers and lasted for several hours. It happened during a public holiday as Muslims, who are the majority in Malaysia, celebrate the second day of Eid al-Fitr. National oil company Petronas said the fire started at one of its gas pipelines at 8:10am and the affected pipeline was later isolated. Disaster management officials said shutting the
DITCH TACTICS: Kenyan officers were on their way to rescue Haitian police stuck in a ditch suspected to have been deliberately dug by Haitian gang members A Kenyan policeman deployed in Haiti has gone missing after violent gangs attacked a group of officers on a rescue mission, a UN-backed multinational security mission said in a statement yesterday. The Kenyan officers on Tuesday were on their way to rescue Haitian police stuck in a ditch “suspected to have been deliberately dug by gangs,” the statement said, adding that “specialized teams have been deployed” to search for the missing officer. Local media outlets in Haiti reported that the officer had been killed and videos of a lifeless man clothed in Kenyan uniform were shared on social media. Gang violence has left
US Vice President J.D. Vance on Friday accused Denmark of not having done enough to protect Greenland, when he visited the strategically placed and resource-rich Danish territory coveted by US President Donald Trump. Vance made his comment during a trip to the Pituffik Space Base in northwestern Greenland, a visit viewed by Copenhagen and Nuuk as a provocation. “Our message to Denmark is very simple: You have not done a good job by the people of Greenland,” Vance told a news conference. “You have under-invested in the people of Greenland, and you have under-invested in the security architecture of this
Japan unveiled a plan on Thursday to evacuate around 120,000 residents and tourists from its southern islets near Taiwan within six days in the event of an “emergency”. The plan was put together as “the security situation surrounding our nation grows severe” and with an “emergency” in mind, the government’s crisis management office said. Exactly what that emergency might be was left unspecified in the plan but it envisages the evacuation of around 120,000 people in five Japanese islets close to Taiwan. China claims Taiwan as part of its territory and has stepped up military pressure in recent years, including
