Four astronauts headed to the International Space Station on Sunday where they will oversee the arrivals of two new rocketships during their half-year stint.
SpaceX’s Falcon rocket blasted off from Kennedy Space Center, carrying NASA’s Matthew Dominick, Michael Barratt and Jeanette Epps and Russia’s Alexander Grebenkin, The Associated Press reported.
The astronauts should reach the orbiting lab on Tuesday. They will replace a crew from the US, Denmark, Japan and Russia, who have been there since August.
“When are you getting here already?” space station commander Andreas Mogensen asked via X, formerly Twitter, after three days of delay due to high wind. SpaceX Launch Control termed it “fashionably late.”
There was almost another postponement Sunday night. A small crack in the seal of the SpaceX capsule's hatch prompted a last-minute flurry of reviews, but it was deemed safe for the whole mission.
The new crew's six-month stay includes the arrival of two rocketships ordered by NASA. Boeing’s new Starliner capsule with test pilots is due in late April. A month or two later, Sierra Space’s Dream Chaser, a mini shuttle, should arrive. It is for delivering cargo to the station, but not passengers yet.
Epps was originally assigned to fly Boeing’s Starliner, which got bogged down with problems and stalled. NASA finally switched her to SpaceX.
“I am in a New York state of mind right now, it is amazing," she said upon reaching orbit, referring to the Billy Joel song.
Epps, who is from Syracuse, NY, is the second Black woman assigned to a long station mission. She said before the flight that she is especially proud to be a role model for Black girls, demonstrating that spaceflight “is an option for them, that this is not just for other people.”
An engineer, she worked for Ford Motor Co. and the CIA before becoming an astronaut in 2009. Epps should have launched to the space station on a Russian rocket in 2018, but was replaced for reasons never publicly disclosed.
Also new to space are Dominick, a Navy pilot, and Grebenkin, a former Russian military officer.
Barratt, a doctor on his third mission, is the oldest full-time astronaut to fly in space. He turns 65 in April.
“It's kind of like a roller coaster ride with a bunch of really excited teenagers,” Barratt said after reaching orbit. As for his age, he said before the flight, “As long as we stay healthy and fit and engaged, we’re good to fly."
Flight controllers are monitoring a growing cabin leak on Russia’s side of the space station. The leak has doubled in size in the past few weeks and the area has been sealed off, NASA program manager Joel Montalbano said. He stressed there is no impact to station operations or crew safety.



Solar Power Companies Are Growing Fast in Africa, Where 600 Million Still Lack Electricity

Companies that bring solar power to some of the poorest homes in Central and West Africa are said to be among the fastest growing on a continent whose governments have long struggled to address some of the world's worst infrastructure and the complications of climate change.

The often African-owned companies operate in areas where the vast majority of people live disconnected from the electricity grid, and offer products ranging from solar-powered lamps that allow children to study at night to elaborate home systems that power kitchen appliances and plasma televisions. Prices range from less than $20 for a solar-powered lamp to thousands of dollars for home appliances and entertainment systems.

Central and West Africa have some of the world’s lowest electrification rates. In West Africa, where 220 million people live without power, this is as low as 8%, according to the World Bank. Many rely on expensive kerosene and other fuels that fill homes and businesses with fumes and risk causing fires.

At the last United Nations climate summit, the world agreed on the goal of tripling the capacity for renewable power generation by 2050. While the African continent is responsible for hardly any carbon emissions relative to its size, solar has become one relatively cost-effective way to provide electricity.

The International Energy Agency, in a report earlier this year, said small and medium-sized solar companies are making rapid progress reaching homes but more needs to be invested to reach all African homes and businesses by 2030.

About 600 million Africans lack access to electricity, it said, out of a population of more than 1.3 billion.

Among the companies that made the Financial Times' annual ranking of Africa's fastest growing companies of 2023 was Easy Solar, a locally owned firm that brings solar power to homes and businesses in Sierra Leone and Liberia. The ranking went by compound annual growth rate in revenue.

Co-founder Nthabiseng Mosia grew up in Ghana with frequent power cuts. She became interested in solving energy problems in Africa while at graduate school in the United States. Together with a US classmate, she launched the company in Sierra Leone with electrification rates among the lowest in West Africa.

"There wasn’t really anybody doing solar at scale. And so we thought it was a good opportunity,” Mosia said in an interview.

Since launching in 2016, Easy Solar has brought solar power to over a million people in Sierra Leone and Liberia, which have a combined population of more than 14 million. The company’s network includes agents and shops in all of Sierra Leone’s 16 districts and seven of nine counties in Liberia.

Many communities have been connected to a stable source of power for the first time. “We really want to go to the last mile deep into the rural areas,” Mosia said.

The company began with a pilot project in Songo, a community on the outskirts of Sierra Leone’s capital Freetown. Uptake was slow at first, Mosia said. Villagers worried about the cost of solar-powered appliances, but once they began to see light in their neighbors’ homes at night, more signed on.

“We have long forgotten about kerosene,” said Haroun Patrick Samai, a Songo resident and land surveyor. “Before Easy Solar we lived in constant danger of a fire outbreak from the use of candles and kerosene."

Altech, a solar power company based in Congo, also ranked as one of Africa's fastest growing companies. Fewer than 20% of the population in Congo has access to electricity, according to the World Bank.

Co-founders Washikala Malango and Iongwa Mashangao fled conflict in Congo's South Kivu province as children and grew up in Tanzania. They decided to launch the company in 2013 to help solve the power problems they had experienced growing up in a refugee camp, relying on kerosene for power and competing with family members for light to study at night.

Altech now operates in 23 out of 26 provinces in Congo, and the company expects to reach the remaining ones by the end of the year. Its founders say they have sold over 1 million products in Congo in a range of solar-powered solutions for homes and businesses, including lighting, appliances, home systems and generators.

“For the majority of our customers, this is the first time they are connected to a power source,” Malango said.

Repayment rates are over 90%, Malango said, helped in part by a system that can turn off power to appliances remotely if people don't pay.
