This past year was a momentous one in spaceflight, bringing to a close many of the most significant storylines that have dominated this industry in the last 10 to 15 years.
Consider the state of play in 2010: A handful of large government space agencies controlled spaceflight activities. NASA was still flying the venerable space shuttle with no clear plan for deep space exploration. The James Webb Space Telescope remained in development hell. Russia was the world’s dominant launch provider, putting as many rockets into space that year as the United States and China combined. At the time, China’s longest human spaceflight was four days. Much has changed in the last decade or so.
2022 was a watershed moment because so many of the major stories since 2010 reached their denouement. In this sense, it feels like the end of an era and the opening of a new one in spaceflight. This story, therefore, will look back at five of these major space storylines and then attempt to forecast what some of the dominant storylines for the remainder of the 2020s will be.
An exciting but uncertain road lies ahead. Looking back
James Webb Space Telescope. NASA spent about two decades and $10 billion developing this massive, complex space telescope. It was subject to countless articles describing all of its potential breakthroughs but also its endless cost overruns and delays.
The telescope finally launched on Christmas Day 2021 and then spent the first half of 2022 undergoing an extensive deployment process and commissioning of its scientific instruments. But when astronomers finally turned it toward the heavens, Webb delivered wonders. Advertisement
The process of designing, building, and testing this telescope on the ground took so long and required so much money that we may never see such a telescope again. The next one may be assembled in space rather than on the ground. Regardless, the era of Webb’s development is over. The era of its discovery has begun.
May it live long and prosper. Enlarge / The James Webb Space Telescope captured a stunning new view of the iconic Pillars of Creation.
Space Launch System. This was another massive development program by NASA in the 2010s, during which the space agency sought to build a super heavy-lift rocket. The program consumed about $20 billion. But whereas the Webb space telescope incorporated many new elements and represented cutting-edge technology, the SLS rocket did not.
The rocket was controversial from the beginning because the SLS reconstituted parts of the space shuttleits main engines, its solid rocket boosters, and even the diameter of its core stage was an exact match for the external fuel tank of the shuttle. This rocket was justifiably seen as a congressionally mandated program to keep workers at NASA and its large contractors, such as Boeing and Northrop, gainfully employed. The justification for this decision was increasingly insupportable as the 2010s progressed and private launch companies such as SpaceX proved far more efficient than the government.
An added pain point is that although the rocket was originally supposed to launch at the end of 2016, it did not take flight until November 2022.
However, once the SLS rocket launched, it performed its mission flawlessly. The Artemis I mission got off to an excellent start with the SLS rocket inserted Orion into its target orbit, a notable feat for a debut launch. So ends the saga of “Block 1” development of the SLS rocket. It’s nice when space stories have a happy ending.

Labour will eliminate unauthorised sewage spillages in 10 years, the environment secretary has told Sky News.
Steve Reed also pledged to halve sewage pollution from water companies by 2030 as he announced £104 billion of private investment to help the government do that.
“Over a decade of national renewal, we’ll be able to eliminate unauthorised sewage spillages,” he said.
“But you have to have staging posts along the way, cutting it in half in five years is a dramatic improvement to the problem getting worse and worse and worse every single year.”
He said the water sector is “absolutely broken” and promised to rebuild it and reform it from “top to bottom”.
His earlier pledge to halve sewage pollution from water companies by 2030 is linked to 2024 levels.
The government said it is the first time ministers have set a clear target to reduce sewage pollution and is part of its efforts to respond to record sewage spills and rising water bills.
Ministers are also aiming to cut phosphorus – which causes harmful algae blooms – in half by 2028.

Mr Reed said families had watched rivers, coastlines and lakes “suffer from record levels of pollution”.
“My pledge to you: the government will halve sewage pollution from water companies by the end of the decade,” he added.
Addressing suggestions wealthier families would be charged more for their water, Mr Reed said there are already “social tariffs” and he does not think more needs to be done, as he pointed out there is help for those struggling to pay water bills.
The announcement comes ahead of the publication of the Independent Water Commission’s landmark review into the sector on Monday morning.
The commission was established by the UK and Welsh governments as part of their joint response to failures in the industry, but ministers have already said they’ll stop short of nationalising water companies.
Mr Reed said he is eagerly awaiting the report’s publication and said he would wait to see what author Sir John Cunliffe says about Ofwat, the water regulator, following suggestions the government is considering scrapping it.
On Friday, the Environment Agency published data which showed serious pollution incidents caused by water firms increased by 60% in England last year, compared with 2023.

Why sewage outflows are discharging into rivers
Meanwhile, the watchdog has received a record £189m to support hundreds of enforcement officers for inspections and prosecutions.
“One of the largest infrastructure projects in England’s history will clean up our rivers, lakes and seas for good,” Mr Reed said.
But the Conservatives have accused the Labour government of having so far “simply copied previous Conservative government policy”.
“Labour’s water plans must also include credible proposals to improve the water system’s resilience to droughts, without placing an additional burden on bill payers and taxpayers,” shadow environment secretary Victoria Atkins added.
The Rivers Trust says sewage and wastewater discharges have taken place over the weekend, amid thunderstorms in parts of the UK.
Discharges take place to prevent the system from becoming overwhelmed, with storm overflows used to release extra wastewater and rainwater into rivers and seas.
Water company Southern Water said storm releases are part of the way sewage and drainage systems across the world protect homes, schools and hospitals from flooding.
In a village in Ladakh, there was experienced an eruption in the sky which turned the sky into red and green auroras on May 10, 2024. This has not been seen in the past 10 years. It got triggered by the fiery solar storm, called Coronal Mass Ejections (CMEs) which are magnetised and thrown from the Sun at a million km per hour distance. Such arruptions in masses, triggered by the filament eruptions and solar flames sped to millions of kilometer towards our planet. This kind of rare aura has been ignited from the fiery solar storm.
Indian Scientists Investigate
According to organiser, The indian scientists’ team, led by Dr. Wageesh Mishra, used the data from NASA, ESA and other ground facilities to find this auroral phenomenon at the Indian Astronomical Observatory, by applying the Flux Rope Internal State (FRIS) model in order to broaden the coronograph images. The evolving temperature, magnetic fields and structure of the Coronal Mass Ejections were mapped at the time of interplanetary journey. This is the first global study to chronicle CME thermal dynamics from the Sun to Earth, which is published in Astronomy & Astrophysics.
Unexpected Reheating of CMEs
In contrast to the expectations, the CMEs didn’t cool with their expansion. In fact, they heat up at their midway, absorbing heat and maintaining a constant temperature over time they impact Earth. This thermal restructuring is due to the collision of two CMEs, where the electrons release high temperatures and ions release mixed lower and higher temperatures predominantly.
Magnetic Collision Triggers Lights
Data from NASA’s Wind Spacecraft, when a solar storm reached Earth, shows that the plasma covered Earth in double flux ropes. These are twisted magnetic structures which can trigger potential geomagnetic disturbances. Such an entangled magnetic field brought auroras as far south. i.e. Ladakh, and produces a spectacular light show that was seen by the citizens of that place.
Global Impact and Research Breakthrough
This finding held significant implications for global space weather forecasting and India. Through the understanding of the interaction of CMEs’ thermal and magnetic changes, the scientists could better develop the early-warning systems for power grid issues, navigation outages and satellite disruptions.
