AFTER peering inside Nasa’s broken Genesis capsule with flashlights and mirrors, scientists said on Friday the craft’s unexpected crash landing left solar material intact and most scientific objectives within reach
“We should be able to meet most if not all of our primary science goals,” Roger Wiens, a key scientist on the project, said at a telephone news conference. “Overall, we’re quite confident that we can achieve a high degree of success from a science point of view.”
The $264 million mission was designed to collect charged solar particles on delicate wafer-like plates and return them to Earth for examination. The wafers were believed to be so fragile that a helicopter-assisted parachute landing was planned. But the parachute failed to deploy on Wednesday, sending Genesis hurtling to Earth at 320km/h.
The crash left Genesis cracked and embedded in the Utah desert, and scientists were demoralized at first, said Don Sevilla, the lead engineer in the recovery project.
But after the capsule was flown to a “clean room” at the U.S. Army Dugway Proving Ground in Utah, “We had great cause for optimism,” Sevilla said.
An intensive look inside the cracked capsule using flashlights and small mirrors indicated large pieces of the particle-collecting wafers were intact, Sevilla said.
“We do not need to have whole pieces to do our science,” he told reporters. “We do know that we have samples of everything we are trying to collect.”
Scientists and engineers plan to start peeling back the layers of the breached craft on Saturday but the total investigation will probably take months.
The main challenges are contamination and abrasion from the Utah soil, the scientists said.
However, Sevilla said the first glimpses inside the capsule show it to be surprisingly clean, given its violent landing. “We’re not talking about great clods of dirt” on the spacecraft’s interior, he said.
The charged particles of solar wind, ejected from the upper atmosphere of the sun, are expected to help scientists learn how the sun and planets formed some 4.5 billion years ago, and could give clues on the evolution of the solar system.

Swedish science prize
A Dutch professor became the first recipient of a new Swedish science prize in the field of medical education research, the awarding body said on Monday.
The Prize for Research in Medical Education 2004, worth $61,300, was awarded to Professor Henk G. Schmidt, of the University of Erasmus, Rotterdam, for his original and groundbreaking research into medical education research, the Karolinska Institutet said.
Schmidt was cited for “his outstanding research into learning at all levels, from student to medical specialist.”
The purpose of the prize is to stimulate research in medical education to promote long-term improvements of educational practices in medical training, the institute said.
The award will be conferred every three years to an eminent researcher, Swedish or foreign, working in a field related to professional health care training and will be presented on Nov. 4, the institute said.
The Karolinska Institutet also awards the Nobel prize for physiology or medicine each year. That prize will be awarded Oct. 4. — Scit-tech World Report
